JAMESF. DAVIS, OF FALL RIVER, MASSACHUSETTS.

GUN-CLEANER.

SPECIFICATION forming part of Letters Patent No. 247,541, datedSeptember 2'7, 1881,

Application filed July 20, 1881. (No 'model.) A

To all whom it may concern Be it known that I, JAMEs F. DAVIS, of

Fall River, in the county of-Bristol, in the State of Massachusetts,have invented a new and useful Improvement in Gun-Cleaners;

cleaner, atits entering end, with a tubular reservoir to contain acleansing-fluid, which fluid is discharged from said reservoir through asuitable vent between two swabs, which fit snugly the bore of thegun-barrel, and also in the use of elastic swabs which can be adjustedand spread diametrically between metallic washers by the pressure of ascrew. v

The gun-cleaner A is made, as usual, with one or more joints screwedtogether to form a continuous rod. The .joint B is made tubular andforms a chamber or reservoir, in which I pour any suitablecleansing-fluid. I prefer to use benzine for this purpose because by itssolvent properties it is admirably adapted to efle'ct and remove fromthe gun-barrel the residuum of the burned powder. The lastjoint, O, is asolid cylindrical piece,screwed into the outer end of the chamber B, andprovided with a small central bore, a, which opens into the chamber B atits outer end and terminates, midway .the length of the rod 0, in avent, b. The cylindrical rod 0 is shouldered at c c, as shown, and hasmetallic washers or collars D D D D, between which are the swabs E E,respectively. The swabs are made of any suitable material, preferablyindia-rubber, because of its elasticity. They should be of a diameternearly equal to that of the gun-bore. A nut, F, at the end of the piece0 confines the swab E and the collars D D in position.

The gun-barrel is shown in longitudinal section at G in Fig. 1.

The swabs, being elastic, are capable of diametrical expansion bycompressing them between the metallic collars, and so can be adjusted,as desired, to flt snugly the bore of the gun. -ForthispurposeItightenthenutF, which presses the outer collar, D, against the swab E. As theinner collar, D, has a rigid bearing against the shoulder c of the joint0, the swab E must spread or expand outwardly. I then enter theimplement into the gun-barrel, and whenitis inserted Ican still furtheradjust it by turning the handle, which has the same effect to spreaddiametrically the swab E as the turning of the nut has upon the swab E,asbefore described. When the swabs have been thus adj usted to snuglyfit the bore, it will be perceived that I have formed within thegun-barrel a temporary chamber, of which the two swabs form the ends,andtheinner surface of the gun-barrel the sides, and into the temporarychamber so formed the cleansing-fluid enters, flowing from the reservoirB through the duct a b, and comes into direct contact with the surfaceof the bore to be cleaned, between the swabs. As the implement is movedup and down the barrel all of the inner surface of the bore isconsecutively exposed to the fluid, and the edges of the swabs scoursaid surface, while at the same time. the fluid cannot flow away, beingconfined between the swabs, as described.

It would obviously be within my invention if the reservoir should heformed in the handle of the implement instead of forming a part of therod itself, and should discharge the fluid by a suitable duct runningthroughout the entire length of the rod.

I am aware that the use of the rubber swabs laterally expansible by thepressure of a screw is not new, and also that gun-cleaners have beenconstructed containing a reservoir and duct for holding and conveying acleansingfluid; but

I claim as a novel and useful invention and desire to secure by LettersPatent- The improved gun-cleaner herein described, consisting of thejoints A, the tubular reservoir B, the perforated joint 0, the collars DD D D, the swabs E E, and the nut F, combined and operatingsubstantially as and forthe purpose specified.
